How to Fish Missouri (below Holter): Tips & Tactics

The Missouri is a technical tailwater demanding precise presentations. Match the hatch exactly and fish light tippet (5X-6X). The sow bug and scud patterns produce year-round.

Best Times of Day

Morning hours offer consistent fishing. During summer, focus on early morning Trico spinner falls and evening caddis activity. Midday fishing can be excellent during winter with midge hatches.

Recommended Techniques

During Trico hatches, fish the spinner fall. The river fishes best from a drift boat allowing access to prime lies. For wade fishing, focus on the edges and back eddies.

Water Conditions

Stable flows from the dam create consistent fishing. Water temperatures remain cold year-round due to dam releases. Optimal fishing occurs between 4,000-8,000 CFS.

Fly Selection

Sow bugs and scuds are the bread and butter patterns. RS2 and Lightning Bug nymphs work year-round. Match the prolific mayfly hatches when active.

Local Knowledge

Craig is the center of Missouri River fishing culture. Book guides well in advance for peak seasons. The river can handle pressure but respect other anglers.

Local Tips

This is match-the-hatch fishing at its finest. The town of Craig revolves around trout fishing with multiple outfitters and lodges.
